Paper Abstract

The orientation and attachment of neuronal cells were controlled by submicron-scale topographical patterns. The surface structure is realized with a laser beam and photo-responsive azobenzene polymer thin films. A surface relief grating (SRG) can be produced by self-organization of molecules under the action of light. The cells are attached onto the SRG and preferentially grown along the groove direction. The use of polymer thin films is good candidate for cellular engineering applications.
